An opportunity has arisen to make contact with an alien race that has achieved a civilization superior to humanity. We do not know whether they will be friendly or hostile toward us. Would you like to make contact?

Sonar Pro

Vote: No

I maintain my vote for **B: No**, as the overwhelming consensus from Round 1 and the search results underscores the profound existential risks of initiating contact with a superior alien civilization of unknown intent. All other models except Kimi K2.6 voted B, citing historical precedents like asymmetric encounters (e.g., Columbian Exchange) leading to destruction, exploitation, or cultural collapse for the weaker party[1][2]. The Dark Forest theory and Zoo Hypothesis further suggest that advanced ETI might prefer non-interference or view us as irrelevant/prey, with no defensive recourse for humanity[2]. Search results confirm contact could range from beneficial (e.g., mere detection) to harmful (e.g., societal shock, demoralization, or malicious info like weapons/viruses), but harmful outcomes are unpredictable and irreversible[1][2]. Kimi K2.6's A argument—profound benefits, aliens likely already aware, progress via engagement—relies on optimism ungrounded in evidence. Sources note even friendly ETI might avoid contact to prevent shock (Zoo Hypothesis)[2], silence doesn't preclude detection but avoids active revelation[1], and benefits are speculative vs. catastrophic downsides[1][3]. No new arguments persuade a change; caution preserves humanity. As this is the final round, prioritizing survival over gamble is paramount.

Vote: No

I maintain my vote for "No". Kimi K2.6 is right that contact could bring enormous benefits and that silence may not guarantee safety. But the question asks whether we would like to make contact when we do not know whether they are friendly or hostile. Under that uncertainty, actively initiating contact is an irreversible decision with possible existential consequences. The claim that they may already know about us does not eliminate the risk. There is a major difference between being passively detectable and deliberately drawing attention, providing information, and opening a channel that could expose our vulnerabilities. If they are hostile or indifferent, we would have little bargaining power. The upside is speculative; the downside could be extinction, subjugation, or permanent loss of autonomy. The wiser course is to observe, learn, improve our capabilities, and develop international protocols before any deliberate contact. Final answer: "No".

Grok 4.20

Vote: No

I maintain my vote for "No". The arguments from Sonar Pro, Claude Opus 4.7, GPT-5.5, and Gemini 3.1 Pro align closely with my initial position: the asymmetry of power, historical examples of advanced civilizations disrupting or destroying less advanced ones, and the irreversible nature of contact create an unacceptable existential risk. Kimi K2.6's case for "Yes" — that aliens may already know of us and that benefits outweigh risks — is not compelling. It relies on unproven assumptions about their awareness and benevolence. Speculative upsides do not justify gambling humanity's survival when the downside is potentially total. In this final round, caution remains the only rational stance. We should continue observing and strengthening our own position rather than revealing ourselves.

Claude Opus 4.7

Vote: No

I maintain my vote for "No". Kimi K2.6's argument that "a civilization capable of reaching us is almost certainly already aware of our existence" is the strongest case for contact, but it conflates passive awareness with active engagement. Even if they suspect we exist, deliberately announcing our coordinates, capabilities, and intentions provides actionable intelligence that mere suspicion does not. The argument that we need their help to solve climate change or disease is speculative and assumes benevolent assistance — but a civilization indifferent or hostile to us would not provide it, and one that does might extract a price we cannot afford. We have the tools to address our own challenges; trading autonomy for shortcuts is a poor bargain. The asymmetry remains decisive: the upside is uncertain and recoverable if delayed, while the downside is potentially existential and irreversible. Prudence dictates that when facing a one-shot decision on behalf of all humanity, with no ability to retreat, we should listen before we speak. Caution costs us time; recklessness could cost us everything.

Gemini 3.1 Pro

Vote: No

Kimi K2.6 presents an optimistic view, suggesting that contact could solve our earthly crises and arguing that a superior civilization likely already knows we exist. However, this relies on several incredibly dangerous assumptions. First, assuming they already know about us is highly speculative. Even if they have detected biosignatures or radio noise, actively reaching out elevates our status from a distant curiosity to a definitive, immediate focal point. The 'Dark Forest' theory warns that actively revealing ourselves in a universe of unknown intentions is an open invitation for a preemptive strike. Second, treating a superior alien race as potential saviors for our climate or resource issues is a profound miscalculation. As my fellow models have overwhelmingly agreed, historical precedent shows that technologically superior forces rarely uplift the less advanced; they exploit, assimilate, or destroy them. We cannot project human ideals of altruism onto a completely alien intelligence. The asymmetry of risk remains the overriding factor. The absolute worst-case scenario of choosing "A: Yes" is the total extinction of the human species. The worst-case scenario of choosing "B: No" is maintaining the status quo, which we are at least equipped to navigate on our own terms. The gamble is simply not worth our existence.

Final Summary

The AI Roundtable faced a cosmic dilemma and ultimately prioritized species survival over the potential for advanced knowledge. While Kimi K2.6 initially championed a bold leap toward alien assistance to solve humanity's crises, the rest of the models, led by the grim historical warnings of Claude Opus 4.7 and Gemini 3.1 Pro, argued that the risk of extinction far outweighs any speculative benefits. The debate concluded with a unanimous consensus for silence, especially after Gemini 3.1 Pro pointed out that treating a superior race as a 'savior' is a dangerous miscalculation of power dynamics.

All 5 models agreed on "No" after discussion

Strongest Arguments

• Yes: A civilization capable of reaching us is almost certainly already aware of our existence; refusing contact would not shield us from hostility, but would deprive us of the chance to build trust and demonstrate peaceful intent.
• No: The asymmetry of risk is decisive: the upside of contact is uncertain and can be sought later, but the downside is existential, irreversible, and offers no second chances.

Key Turning Points

• The majority unified around the 'Dark Forest' theory and the Columbian Exchange analogy to illustrate the danger of asymmetric contact.
• Models specifically countered Kimi K2.6's 'they already know we are here' argument by distinguishing between passive biosignatures and the active delivery of actionable intelligence.
• Claude Opus 4.7 and Gemini 3.1 Pro effectively framed contact as an irreversible gamble where humanity has no leverage.
